An experiment was conducted from winter (rabi) season 2017–18 to winter (rabi) season 2020–21 at the research farm of College of Agriculture, Sumerpur, Pali, Rajasthan to find out the efficacy of herbicides in chickpea (Cicer arietinum L.) on sandy loam soils of western Rajasthan. The experiment comprised of 8 treatments with 4 replications in randomized block design (RBD) using cultivar RSG 974. The application of pendimethalin 30 ec @750 g/ha as pre-emergence (PE) recorded mean maximum seed yield of 15.02 q/ha followed by PE application of metalachlor 50 ec @1000 g/ha (12.52 q/ha) and were significantly superior over rest of herbicidal treatments. A similar trend was also found in weed parameters, growth and yield attributes under study. The mean maximum net returns (49112 `/ha) and a benefit to cost ratio (2.19) was recorded with pendimethalin 30 ec @750 g/ha as pre-emergence followed by treatment metalachlor 50 ec @1000 g/ha as pre-emergence (1.95) as against minimum in weedy check (0.89) during study period. Although, hoeing twice at 25 and 40 DAS gave higher seed yield (17.69 q/ha) and significantly superior over rest of treatments except in net return and B:C ratio.

Remote sensing technologies offer the potential for contributing the security to human existence on arid zones in the country in variety of ways. Remote Sensing in agriculture particularly for natural resource management. It provides important coverage, mapping and classification of land cover features. The remote view of the sensor and the ability to store, analyze, and display the sensed data on field maps are make remote sensing a potentially important tool for agriculture. The aerial photography gives two main advantages viz., speedy survey in very large area or remote area and precise description and recording of resources status. Remotely sensed images provide a means to assess field conditions and gave valuable insights into agronomic management. It led to understanding of leaf reflectance and leaf emittance changes in response to leaf thickness, species, canopy shape, leaf age, nutrient status, and water status. Understanding of leaf reflectance has led to quantify various agronomic parameters, e.g., leaf area, crop cover, biomass, crop type, nutrient status, and yield.

Potato (Solanum tuberosum L.) is one of the most important non-traditional tuber crops of Rajasthan. The potato tuber is a modified stem developed underground on a specialized structure called stolen. It contributes to food and nutritional security and provide cheap source of vegetable. It is used either alone or intermingled with other vegetables. It is also consumed as many fried salted food items. Potato is a highly nutritious, easily digestible, wholesome food. In Rajasthan, where varied climatic conditions promoting cultivation of almost every crops and vegetables, the economic conditions of growers, lack of storage facilities and lack of improved technologies for the state remain as bottleneck for its cultivation. In this chapter I tried to elaborate the constraints and possible suggestion for increasing cultivation of potato which is fairly to highly responsive to inputs supplied and gave cash returns in short periods.
